What does it mean that the two-door framework?

One-way doors deserve careful analysis — two-way doors should be walked through quickly.

Example: You spend three weeks evaluating which project management tool to adopt. You research features, read comparisons, run trials, build spreadsheets. Then you realize: if the tool doesn't work, you migrate in a weekend. That was a two-way door. Meanwhile, you signed a two-year vendor contract with a 30-day evaluation window and barely glanced at the terms. That was a one-way door — and you treated it like a minor errand.

Try this: List your five most recent decisions that took more than a day to make. For each one, answer: if this decision turns out badly, can I reverse it within a week at low cost? Mark each as a one-way door or a two-way door. Count how many two-way doors consumed disproportionate deliberation time. For each of those, write what you would do differently — the specific point where you would have stopped analyzing and walked through.
